How Do Fiber Optic Internet and Cables Work?

Fiber optic lines are made using a special type of glass. They are long and thin strands that are no wider than any strands of hair on your head. Many strands are grouped together to create optical cables, which work by transferring light signals to your home TVs and computers.

Optical fibers can either be single-mode or multi-mode fibers. In a single-mode fiber the cores are small. These cores are used to send infrared laser lights to your electronic devices. The cores found in multi-mode fibers are larger and move infrared lights transferred away from the diodes that emit the light.
While some optical fibers are made from glass others are made from plastic. This type of optical fiber takes visible red lights from an LED to your Internet connected devices.
An optical fiber is made up of the cladding, the core and the buffer coating. The cladding consists of materials found on the outside of an optical fiber that hold the core as the light reflects into it. The core is simply the center of the fiber, and is made of glass. The buffer coating is used to keep the fiber from becoming wet or otherwise damaged.
Light travels through the fiber optic lines due to a principle referred to as total internal reflection. This allows the light to travel from its point of origin due to the fact that light from the core is never absorbed by the cladding.
Since the glass used to make optical fibers contains impurities, a part of the light signal always degrades. The speed at which it degrades is entirely dependent upon the number of impurities in the glass as well as the light signal’s wavelength. Premium fibers degrade much less than other fibers do.

Fiber Optic Cables
Fiber optic cables contain relay systems made up of the optical fiber, regenerator and receiver, as well as a transmitter. The regenerator is responsible for giving the light signal a boost and contains fibers covered with doping. The receiver takes the incoming signals and decodes them and the transmitter encodes the signals and sends them to your computer and your TV.
So what does all of this mean to you? It means that when you send an email or otherwise communicate data to someone else via the Internet, an electrical signal that comes directly from your computer passes through an optical network terminal and is then reconverted to a light signal. This signal is then sent through the fiber optic cables to its intended recipient. For this reason, fiber optic cables can allow you fast and smooth Internet access and information transmission. Information is transferred at a higher rate of speed through fiber optic cables than anything else.
Small businesses usually do well with fiber optic Ethernet cables. These cables allow them to easily and effectively run their internal and external communications smoothly and efficiently. This technology has revolutionized the world of computer and telephone communications. It is now used in homes and businesses all across the country.

This is such a nice post. Thank you very much for sharing this. I have learned something new today especially on how fiber optic and internet and cable works. I really didn’t know that fiber optic cables can allow us fast and smooth Internet access and information transmission.
